Just passing through a bifrost graph takes a long time :(

I'm in Maya2020.3 with version 2.1.0.0 of Bifrost.  I have an array of 5000+ positions as input.  I added an "enable" attribute in an attempt to speed things up.  If "enable" is off, I just pass the positions through the graph without any operations being performed.  And it's considerably slower than having 5000+ parent constraints.  Why?

Converting Maya native data to Bifrost has a cost. Even if you are not doing anything in the graph, the data will be converted twice. Once to go inside Bifrost, and a second time to go back to Maya.

I wasn't aware of the conversion process.  Thank you for the info.

Just thinking out loud...meshes seem to go into Bifrost pretty quickly.  If I somehow create a dummy mesh from my 5000+ positions and pass that into Bifrost, would that be any faster?

Maya Meshes also have to be converted to go inside Bifrost, but maybe doing it this wat is faster. Try and let us know 🙂

Seems like it should be faster.  I've taken character meshes into Bifrost with much more than 5000 vertices.  And it's way faster than what I'm experiencing now.  I'll let you know.
